Default DPI Gen IV Questions

I just installed a DPI Gen IV on a neighbors 2014 RXV. It seems to be working but it doesn't illuminate the green charge LED on the cart. Is that normal?

Also, anyone know what the float voltage should be? 52 volts or so?

I've used their older chargers before on club cars but this is the first time with this charger and on an EZGO cart.

Hope this helps...

The green LED on the cart will not illuminate with a DPI charger. That is normal.

They really need to rewrite that manual. It says in the manual that the green light comes on when the batteries are charged and in the float mode.

The green light On the charger, the led on the cart has nothing to do with DPI, or their manual.

Update: The charger wasn't going into the trickle charge mode so I called DPI to ask them why or if there was a different dip switch setting for it. I was told that this Gen IV charger doesn't have the trickle charge that keeps the batteries hot. Is that the case?

Mine doesn't have the trickle charge. It goes into what DPI now calls FLOAT. Once the batteries are charged the internal A/C relay disconnects A/C power. The charger then monitors the batteries. The instructions say the charger will start a new charge cycle if the battery voltage gets low enough or after 45 days. Whichever one comes first. I've never left my cart long enough without using it to have a new charge cycle start.

Looking at the instructions and the schematics it looks like the R models have the relay and the smaller Q models don't. The instructions say if it has the relay it will disconnect A/C power and Float and If it doesn't have the relay it will go to maintenance mode. Maintenance mode seems to be the trickle charge mode on the Gen IV chargers.

Guess we are back to explaining the difference of "trickle" and "float" as it pertains to batteries. Float is what you want, it is applying enough current to meet but not exceed a target voltage (above "at rest" & below gassing voltage). Trickle applies a certain amount of current, without a predetermined target voltage to meet or stop increase at. Trickle is undesirable because it can (and likely will) push the batteries into gassing voltage. Above gassing voltage is when electrolytes are consumed, and with no one around to keep the fluid levels up, your batteries will be destroyed.
